DEVICE OR, MACHINE FOR INSERTING FILLER-BARS IN BEATER-ROLLS.

Specification of Letters Patent.

Patented Sept. 3, 1918.

Application filed November 24, 1917. Serial naeoases.

To all whom it may concern:

Be it known that I, CLEMENT F. SIssoN,

' a citizen of the United States, residing at WVhite Pigeon, in thecountyof St. Joseph and State of Michigan, have invented certain new anduseful Improvements in Devices or Machines for Inserting Filler-Bars inBeater-Rolls, of which the following is a specification.

This invention relates to a device or ma chine for inserting filler barsin beater rolls. It has been the common practice to insert the woodenfiller bars in beater rolls by driving them in with sledges. This.requires a good deal of time and effort and frequently results in thesplitting orbreaking of bars and quite conimonlyiirtlie crushing of thegrain of the bars hammered upon.

The main objects of this invention are:

First, to provide a device for inserting filler bars into a beat-er rollby the aid of which the work may be quickly and easily performed andwithout injury to the filler bars, and also, without liability ofbreaking the tiller bars or the beater roll.

Second, to provide a device for this purpose which comprises a hydraulicpress adapted to be motmted on the shaft of a heater roll so that thefiller bars may be gradually forced to position in the roll.

Further objects, and objects relating to structural 7 details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my inventionby the devices and meansdescribed the following specification. The invention is clearly definedand pointed out in the claims. A structure which is :a preferredembodiment of my invention is clearly illustrated in the accompanyingdrawing forming a part of this specification, in which:

Figure I is a detail longitudinal sectlon through a beater rollwith myimproved device moun ted'thereon, the beater roll being shown mainly inconventional form.

Fig. II is "a detail transverse section on a line corresponding to line2-2 of Fig. I.

Fig. III is a detail transverse section similar to Fig. II, with theparts in actuated position.

Fig. IV is a detail horizontal seotlon on a line corresponding to line Hof F g. I.

Fig. 'V is .a vertical transverse section on a line corresponding toline 55 of Fig. V. Fig. VI is an enlarged detail section on a linecorresponding toline 6-6 of Fig. V. i Fig. VII is a side elevation ofone of the filler bars as they are commonly constructed. Fig. VIII is aside elevation of one of the beater bars.

In the drawing,similarreference characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction ofqthe little arrows at the ends of the sectionlines.

lrepresents the shaft of the beater roll supported by bearings 2. Thebeater roll is shown mainly in conventional form and only such parts areillustrated as are deemed necessary to; illustrate my improvements.

" The beater roll, designated generally by the numeral 8, comprisesspiders 4 carrying the iron beater bars 5 between which the filler barsare inserted. The opposed sides of-the bars 5are shaped so as to retainthe filler b-arswhen inserted. This shape makes it necessary to exertconsiderable force on the filler bars in insertingthemand'it is thiscondition which frequently causes the injury or destruction of thefillerbars when driven to place by means of sledges, besides the largeamount of labor required.

I provide a yoke-shaped frame comprising side members 7 and cross member8. The cross member is preferably an I-beam as shown in Fig. V. Theframe is of such di mensions that it is adapted to embrace the beaterroll,with the side members 7 resting upon the beater roll shaft at eachside of the beater roll, as shown in Fig. I. The

ends of the arms have seats 9 therein for the shafts. The U-shape-dtie-rods 10are adapted to embrace the shaft and their ends are disposedthrough cross pieces 11 mounted on the cross member 8 to receive them.

The, tie-rods are detachably secured by means of the nuts 12threaded-upon the ends thereof. Cylinders 13 are mounted upon the crossmember 8 of the frame so that when the frame is mounted upon the shaftof a beater roll the cylinders are supported ra-' d-ially of the beaterroll. The cylinders are open at their inner ends so that the pistons orplungers 14: may be projected therefrom,

as shown in Fig. ill. The prcsser bar 1:) is supported to reciprotmteradially of the shaft 1. by means of the rods 16 which are arrangedthrough the cross member 8 and connected. at their outer ends to theends of the semi-elliptic springs 17 mounted on the cross member. Thisspring yields when the pistons are actuated but is of sutlicient tensionto retract the prcsser bar and also return the pistons to their initialposition. The presser bar is of such width as to pass between the beaterbars 5 so that the inserts may be fully seated, see Fig. III. Thepresser bar has plates 18 secured thereto in alinement with the pistons.

The fluid may be supplied to the pistons under pressure by any suitablemeans but I find a satisfactory means to be a force pump de= gnatedgenerally by the numeral 19 which is mounted on one of the side membersT of the frame and connected by the pipe 20 with the outer ends of thecylinders so that a suitable fluid, such as oil, may be drawn from thestorage tank 21 and forced into the cylinders. Suitable check valves 22are provided in the pump connections to the cylinders. I also provide areturn pipe which is connected with the storage tank 21 and with theouter ends of the cylinders. This pipe is controlled by the valve whichis closed when it is desired to actuate the pistons but which is openedto relieve the pressure and allow the spring 17 to return the presscrbar and pistons to their normal position.

In operation the frame is mounted upon the shaft of a beater roll asshown .in Fig. I. The filler bar is positioned as shown in Fig. H, thevalve 29 of the pump is operated to force the fluid into the cylindersthereby forcing the pistons downwardly and with them the presser bar.When the filler bar is forced to position the valve 2% opened, therebyreleasing the pressure and permitting the spring 1? to return thepresser bar and the pistons, displacing the fluid from the cylindersthrough the pipe connections T he beater roll is then rotated to bringanother filler bar space to position and the operation repeated.

I have illustrated and described my improvements in the form in which Ihave embodied the same in practice. I have not attempted to describevarious modifications and adaptations which I contemplate within thescope of the appended claims as I believe the disclosure made willenable those skilled in the art to which my invention relates to embodyor adapt the same as operating and other conditions may render desirable.
